Mastering Close-up and Macro Flora Photography with Sony 

By Chester Chen

SEL90M28G or SEL100F28GM?

A purpose-built macro lens may automatically come to mind when dealing with floral photography. But in the case of Sony’s Alpha lenses, particularly the SEL90M28G, the mid-range telephoto lens allows you to get really close and take 1:1 magnification images. The lens’ macro capability grants not only magnified shots of the flower’s specific parts, but also its blossoming form.

The SEL100F28GM offers smooth bokeh and a close-focusing mode for beautiful floral close-ups.

However, for capturing flowers about the size of a tennis ball, the SEL100F28GM STF (smooth transition focus) should also be considered. This lens boasts two unique features—exceptionally smooth bokeh (attributed to an internal apodization filter) and a close focusing mode. The former makes creamy and dreamy background blur with sphere-like rendered bokeh balls.

Let’s take a closer look at how these two lenses compare.

As seen in this close-up, Sony’s SEL90M28G brings out the flower’s distinguishing features, thanks to its 1x magnification capability.

With regards to their magnification capabilities, the SEL90M28G features a 1x magnification compared to the SEL100F28GM’s 0.14x magnification. As such, the SEL90M28G is more suited for detailed shots of a flower’s distinguishing features, and extreme close-ups of curious creepy crawlies.

Image quality of both lenses is excellent, as proven by independent trials from non-biased reviewers. Both produced extremely sharp images, but when it comes to bokeh quality, the SEL100F28GM emerges king. The smooth round aperture is the result of the SEL100F28GM’s eleven blades. The SEL90M28G’s nine-blade aperture is more defined, circular, and perfectly rounded.

One disadvantage is the shallow DoF (depth of field), which remains even when you step down to a smaller aperture, such as F11. This can be remedied with Focus Stacking, easily accomplished with a tripod-mounted camera. Without additional hardware, you can select manual focusing and change the focus distance slightly for as many shots as needed to get more of the flower in focus. This stack of images is then loaded into a software application that can detect the sharpness in focus areas; the images are then blended to create a final image. 

Use a macro-focusing rail to take close-ups to the next level.

Get equipped

Utilizing various shooting gear eases the work of a macro photographer. For starters, shooting on a tripod with a solid ball head offers a range of benefits. The tripod enables you to shoot using available light through slower shutter speeds; you can easily compose and recompose. Additionally, you can also use one free hand to operate lights, activate a remote shutter, or simply swat away pesky insects. For serious close-up photographers, I highly recommend using a macro-focusing rail (see above photo for reference). This allows the entire camera to move in a smooth linear motion toward or away from the subject. As it extends outward from the tripod, the rail gives substantial reach to subjects that may be out of reach.

Use Sony’s Imaging Edge mobile application on an external smart device to check your composition and focus more easily.

Sometimes it can be difficult to position the camera on a tripod while keeping an eye on the electronic viewfinder, or even position the camera in a way to view the rear LCD. This is when larger screens, such as your cellphone or a tablet, come in handy. Use Sony’s Imaging Edge mobile application to connect your Sony Alpha camera over Wi-Fi. This enables you to remotely control the settings and check your composition and focus.

Here are some additional items that you can have on hand.

-  Small spray misting bottle with distilled water
-  Colored cards that can be used as a backdrop to obscure messy backgrounds
-  Small handheld LED light(s) to illuminate the flowers
-  Small foldable reflector to either shade the flowers or reflect additional light on your subject; it can be as                simple as a piece of white or silver card stock


Macro photography starts at home

If you are looking to try out macro and close-up flora photography, you can easily do it in the comfort of your home. Set some flowers in a vase and move it around your home. Once you are satisfied with the background, take advantage of natural light that shines through the window, and capture the shot.

Macro and close-up flora photography can start at home, or in your garden.

Another great place to start is in your garden. If not, head to a public garden or conservatory that houses more unique and specialized flora.  Do take care not to harm the flowers, plants, or insects when photographing.

The high megapixel count of Sony's Alpha 7R IV allows you to crop in-post or enable the APS-C crop mode to effectively “zoom” in on your subject.

Final tip: Use a high-megapixel-count Sony Alpha camera, such as the Alpha 7R III or Alpha 7R IV, and you can either crop in post or enable the APS-C crop mode to effectively “zoom” in on your subject. Even though this will reduce the megapixel count of your photos, there will still be enough megapixel count left for extreme details that are good enough for large digital prints. This is quite common when you do not have a lens capable of doing 2x or 4x magnification.
